Zool also known as Zool: Ninja of the Nth Dimension is a video game originally produced for the Amiga by Gremlin Graphics in 1992.
Zool was intended as a rival to Sega's Sonic the Hedgehog. It was heavily hyped upon its initial release, including being bundled with the newly launched Amiga 1200, although not the AGA version with enhanced graphics which followed later. In 2000 the game was re-released as part of The Best of Gremlin compilation.
Zool is a gremlin "Ninja of the Nth Dimension" who is forced to land on Earth. In order to gain ninja ranking he has to pass seven lands.
The game is a pure platform game, relying on smooth, fast moving gameplay, colorful graphics and a soundtrack by Patrick Phelan which overlaps with the Lotus 3 soundtrack and inspired several modern electro/techno remixes. The game also contains a number of embedded minigames, including several arcade games, a scrolling space shooter and a game accessible only by making Zool play a certain tune on an in-game piano or finding certain invisible warp points.
Zool was also ported to the Atari ST, Game Boy, Sega Mega Drive, SNES, Master System, Sega Game Gear, Amiga CD32, PC, Acorn Archimedes, and RISC OS platform, as well as for the arcade machines.
